This is what in-situ sensor validation looks like in our backyard. To kick off data collection for NOAA Fisheries Pacific Islands, lead scientist Dr. Jamison Gove dives to the sinker of the Wave Glider’s Winch to take a water sample next to the Turner C3 fluorometer. Collecting chlorophyll-a, turbidity, and dissolved organic matter water samples at the beginning and end of the mission ensures that electronic measurements from the instrument can be validated.
Chlorophyll-a is an important indicator for estimating phytoplankton biomass in the ocean, which provides insights into the overall health of the marine ecosystem and the abundance of fish. The three Wave Gliders for this survey are equipped with numerous sensors above and below the surface collecting air temperature, wind, barometric pressure, ocean waves, currents, water temperature and salinity. In addition, automated winches with mounted fluorometers allow for the measurement of chlorophyll-a, turbidity, and dissolved organic matter to depths of 150 m.
